(A) Reporting
source water monitoring results.
(1) Systems
shall report results from the source water monitoring required by paragraphs
(A) to (H) of rule
3745-81-65
of the Administrative Code no later than ten days after the end of the first
month following the month when the sample is collected.
(2) All systems serving at least ten thousand
people shall report the results from the initial source water monitoring
required by paragraph (A) of rule
3745-81-65
of the Administrative Code to the primacy agency at the time of this
requirement electronically. If a system is unable to report monitoring results
electronically, the system may use an alternative approach for reporting
monitoring results that the primacy agency approves.
(3) Systems serving less than ten thousand
people shall report results from the initial source water monitoring required
by paragraph (A) of rule
3745-81-65
of the Administrative Code to the primacy agency at the time of this
requirement.
(4) All systems shall
report results from the second round of source water monitoring required by
paragraph (B) of rule
3745-81-65
of the Administrative Code to the director.
(5) Systems shall report the following
applicable information for the source water monitoring required by paragraphs
(A) to (H) of rule
3745-81-65
of the Administrative Code:
(a) Systems shall
report the following information for each Cryptosporidium analysis:
Public water system (PWS) ID;
Source treatment unit (STU) ID;
Sample collection date;
Sample type (field or matrix spike);
Sample volume filtered (L), to nearest 0.25 L;
Was one hundred per cent of filtered volume examined;
and
Number of oocysts counted.
For matrix spike samples, systems shall also report the sample
volume spiked and estimated number of oocysts spiked. These data are not
required for field samples.
For samples in which less than ten liters is filtered or less
than one hundred per cent of the sample volume is examined, systems shall also
report the number of filters used and the packed pellet volume.
For samples in which less than one hundred per cent of sample
volume is examined, systems shall also report the volume of resuspended
concentrate and volume of this re-suspension processed through immunomagnetic
separation.
(b) Systems
shall report the following information for each E. coli analysis:
PWS ID;
STU ID;
Sample collection date;
Analytical method number;
Method type;
Source type (e.g., flowing stream, lake/reservoir, well
designated as surface water);
E. coli/one hundred milliliters;
Turbidity. (Systems serving less than ten thousand people that
are not required to monitor for turbidity in accordance with paragraphs (A) to
(H) of rule
3745-81-65
of the Administrative Code are not required to report turbidity with their E.
coli results.)
(B) Grandfathering previously collected data.
Systems may comply with the initial source water monitoring
requirements of paragraph (A) of rule
3745-81-65
of the Administrative Code by grandfathering sample results collected before
the system is required to begin monitoring (i.e., previously collected data).
To be grandfathered, the sample results and analysis shall meet the following
criteria and shall be accepted by the primacy agency at the time of this
requirement:
(1) A system may
grandfather Cryptosporidium samples to meet the requirements of paragraph (A)
of rule
3745-81-65
of the Administrative Code when the system does not have corresponding E. coli
and turbidity samples. A system that grandfathers Cryptosporidium samples
without E. coli and turbidity samples is not required to collect E. coli and
turbidity samples when the system completes the requirements for
Cryptosporidium monitoring in accordance with paragraph (A) of rule
3745-81-65
of the Administrative Code.
(2)
E. coli sample analysis. The analysis of E. coli samples shall
meet the analytical method and approved laboratory requirements of paragraphs
(H) to (J) of rule
3745-81-27
and rule
3745-89-11
of the Administrative Code.
(3) Cryptosporidium sample analysis. The
analysis of Cryptosporidium samples shall meet the following criteria:
(a) Laboratories analyzed Cryptosporidium
samples using one of the following analytical methods:
(i) USEPA method 1623, "Cryptosporidium and
Giardia in Water by Filtration/IMS/FA" United States environmental protection
agency, 2005, EPA-815-R-05-002.
(ii) USEPA method 1622, "Cryptosporidium in
Water by Filtration/ IMS/FA" United States environmental protection agency,
2005, EPA-815-R-05-001.
(iii) USEPA
method 1623, "Cryptosporidium and Giardia in Water by Filtration/IMS/FA" United
States environmental protection agency, 2001, EPA-821-R-01-025.
(iv) USEPA method 1622, "Cryptosporidium in
Water by Filtration/ IMS/FA" United States environmental protection agency,
2001, EPA-821-R-01-026.
(v) USEPA
method 1623, "Cryptosporidium and Giardia in Water by Filtration/IMS/FA" United
States environmental protection agency, 1999, EPA-821-R-99-006.
(vi) USEPA method 1622, "Cryptosporidium in
Water by Filtration/ IMS/FA" United States environmental protection agency,
1999, EPA-821-R-99-001.
(b) For each Cryptosporidium sample, the
laboratory analyzed at least ten liters of sample or at least two milliliters
of packed pellet or as much volume as could be filtered by two filters that
U.S. EPA approved for the methods listed in paragraph (B)(3)(a) of this
rule.
(4) Sampling
location. The sampling location shall meet the conditions of paragraph (J) of
rule
3745-81-65
of the Administrative Code.
(5)
Sampling frequency. Cryptosporidium samples were collected no less frequently
than each calendar month on a regular schedule, beginning no earlier than
January 1999. Sample collection intervals may vary for the conditions specified
in paragraphs (I)(2)(a) and (I)(2)(b) of rule
3745-81-65
of the Administrative Code if the system provides documentation of the
condition when reporting monitoring results.
(a) The primacy agency at the time of this
requirement may accept grandfathering of previously collected data where there
are time gaps in the sampling frequency if the system conducts additional
monitoring the primacy agency specifies to ensure that the data used to comply
with the initial source water monitoring requirements of paragraph (A) of rule
3745-81-65
of the Administrative Code are seasonally representative and
unbiased.
(b) Systems may
grandfather previously collected data where the sampling frequency within each
month varied. If the Cryptosporidium sampling frequency varied, systems shall
follow the monthly averaging procedure in paragraph (A)(5) of rule
3745-81-67
of the Administrative Code, as applicable, when calculating the bin
classification for systems.
(6) Reporting monitoring results for
grandfathering. Systems that request to grandfather previously collected
monitoring results shall report the following information by the applicable
dates listed in this paragraph. Systems shall report this information to the
primacy agency at the time of this requirement.
(a) Systems shall report that they intend to
submit previously collected monitoring results for grandfathering. This report
shall specify the number of previously collected results the system will
submit, the dates of the first and last sample, and whether a system will
conduct additional source water monitoring to meet the requirements of
paragraph (A) of rule
3745-81-65
of the Administrative Code. Systems shall report this information no later than
the date the sampling schedule is required by paragraph (I) of rule 3745-81-65
of the Administrative Code.
(b) No
later than two months after the applicable date listed in paragraph (C) of rule
3745-81-65
of the Administrative Code, systems shall report previously collected
monitoring results for grandfathering, along with the following associated
documentation:
(i) For each sample result,
systems shall report the applicable information in paragraph (A) of this
rule.
(ii) Systems shall certify
that the reported monitoring results include all results the system generated
during the time period beginning with the first report result and ending with
the final reported result. This applies to samples that were collected from the
sampling location specified for source water monitoring in rule
3745-81-65
of the Administrative Code, not spiked, and analyzed using the laboratory's
routine process for the analytical methods listed in paragraph (B)(3)(a) of
this rule.
(iii) Systems shall
certify that the samples were representative of a plant's source water and the
source water have not changed. Systems shall report a description of the
sampling locations, which shall address the position of the sampling location
in relation to the systems water source and treatment processes, including
points of chemical addition and filter backwash recycle.
(iv) For Cryptosporidium samples, the
laboratory or laboratories that analyzed the samples shall provide a letter
certifying that the quality control criteria specified in the methods listed in
paragraph (B)(3) (a) of this rule were met for each sample batch associated
with the reported results. Alternatively, the laboratory may provide bench
sheets and sample examination report forms for each field, matrix spike,
"Initial Precision and Recovery (IPR)", "Ongoing Precision and Recovery (OPR),"
and method blank sample associated with the reported results.
(7) If the director
determines that a previously collected data set submitted for grandfathering
was generated during source water conditions that were not normal for the
system, such as a drought, the director may determine not to accept the data.
Alternatively, the primacy agency may accept the previously collected data if
the system reports additional source water monitoring data, as determined by
the primacy agency, to ensure that the data set used under paragraphs (A) to
(D) of rule
3745-81-67
of the Administrative Code represents average source water conditions for the
system.
(8) If a system submits
previously collected data that fully meet the number of samples required for
initial source water monitoring in accordance with paragraph (A) of rule
3745-81-65
of the Administrative Code and some of the data are rejected due to not meeting
the requirements of this rule, systems shall conduct additional monitoring to
replace rejected data on a schedule the primacy agency at the time of this
requirement accepts. Systems are not required to begin this additional
monitoring until two months after notification that data have been rejected and
additional monitoring is necessary.
